The recent earthquake occurred off the coast of Russia generated concern in different Pacific countries, including Chili. Although the waves did not cause damage, they reactivated a key question: what is the difference between an alert and an alarm of tsunami?
Both concepts are directly related to the prevention of natural disasters, but they do not imply the same or demand the same actions. Understanding its difference can be vital in emergency moments and make a difference between a scare and a tragedy.
What to do in each case
An alert of tsunami It is broadcast when a great magnitude earthquake occurs in the ocean that could generate a tsunami. At this stage, the authorities monitor the data and prepare the population to a possible evacuation. The objective is that we are attentive and ready to act if the risk increases.
Instead, an alarm of tsunami It is declared when the presence or imminent arrival of dangerous waves has already been confirmed. Here, the evacuation is mandatory and immediate. It is not a warning, but a direct order to get away from coastal areas.
The authorities recommend acting without hesitation before any of these scenarios. If you are on the coast and you feel a strong earthquake or see that the sea withdraws abnormally, you must evacuate towards safe areas, without waiting for official instructions.
Preparing an emergency backpack, knowing the evacuation routes and participating in drills can save lives. The difference between alert and alarm is not only semantic: it implies being ready or acting now.
